It will be understood that the hood 25 is substantially cone-shaped, with cylindrical portion on top.

By means of the devices described the lamp is perfectly insulated. from the lamp-frame and securely held. The lamp-frame is entirely free from liability to become charged, and thus dangerous to persons who have to attend the lamps. lVhen it is desired to cut the lamp out of circuit, this may be readily done by turning the switch-lever 18 into engagement with contacting-piece 19. Aside from this the operation of the electrical lamps is so Well understood as to make specific description of operation unnecessary.

What we claim as new, and desire to secure by Letters Patent, is

1. The combination, With an electric-lamp frame, of insulators 13, adapted to engage and support the lower portion of the lamp, and a ring 7, adapted to surroundthe upper portion of the lamp and secure the same by means of insulating-pieces within the ring, substantially as set forth.

2. The combination, with an electric-lamp frame, of insulators 13, adapted to engage and support the lower portion of the lamp, and a clamping-ring adapted to surround the upper portion of the lamp and engage the same by insulators, substantially as set forth.

3. The combination, with an electric-lamp frame, of the lamp-hood and supporters therefor having a segmental portion on which the edge of the hood rests, and projecting lugs adapted to receive the edge of the hood, and a set-screw for securing the hood, substantially as set forth.

4:. The combination, with an electric-lamp hood, of a supporter therefor having a segmental portion 22, on which the edge of the hood rests, and projecting lugs 22 and 22, adapted to receive the edge of the hood, and a set-screw for securing the hood, substantially as set forth.

5. The combination, with an electric-lamppost frame, of aring 7,surrounding the upper portion of the lamp, and insulators 9 and 9", projecting inside of the ring, and adjustable insulator 9", also projecting inside of the ring, substantially as set forth.

6. In a lamp-frame, the combination of a socket 2, the arms at 4:, projecting therefrom, carrying insulators 13 13 and uprights 5 5, the ring-supporting arms 6, and the ring 7, surrounding the upper portion of the lamp and adapted to engage the same by insulators, substantially as set forth.

7. The combination, in a lamp-frame, of a socket 2, the arms 4, carrying insulators 13, hollow uprights 5 5, ring-supporting arms 6, engaging upon the upperends of the uprights 5, and supporting-ring 7, which is adapted to surround and engage by adjustable insulators the upper portion of the lamp, switchboard 16 and the supports therefor, bindingpost 17 and 18, and switch-lever 1S, substantially as set forth.
